, Patented June 5, 1917.

Application filed May 23, 1916. Serial No. 99,342.

To all whom gtmay concern.

Be it known that I, JULIUS M. COLLINS, a citizen of the United States,residing at Brooklyn, in the county of Kings, State of New York, haveinvented certain new and useful Improvements in Ash-Sifters; and I dohereby declare the followingto be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention belongs to the class of ash sifters, and has particularreference to a gravity sifter. I

The object of the invention, primarily, is to construct a sifterin whichthe presence of dust outside of the sifter is practically eliminated. it

Those sifters which are known to me,even those which confine the asheswithin a sift ing chamber permit more or less dust to escape at theinlet hopper for the ashes and at the exit spout for the cinders.

The presentinvention avoids the presence of dust both at the inlethopper and at the outlet spout for the cinders, a specially con structedcover for connecting the ash pail with the hopper being provided andalso a special connection between the exit spout and the pail forreceiving the sifted material.

My invention further-contemplates a particularly advanta eousarrangement of-gravity screens, whic successively receive the ashes andconduct the siftings to the outlet spouts, and permit the dust orfinematerial to drop into a dust receptacle.

With the above and other objects in view, which will hereinafter appear,my inven tion will now be fully set forth and described, reference beinghad to the accompanying drawing.

In said drawing:- y

Figure l is a front elevation of the sifter,

Fig. 2 is a side elevation thereof,

Fig. 3 is a section on line 33 of Fig. 1,

Fig. 4 is an enlarged detail view of the hopper attachment for holdingthe ash pail, F Fig. 5 is a rear View of the part shown in Fig. 6 is adetail view of the lower end of the spout, looking from below, and i 1Fig. 7 is a detail perspective view of the flexible hood used inconnection with the invention.

Referring more particularly to said drawings, 1 represents a casingwhich is constructed of any'suitable material, as metal or wood, andtapers laterallyfrom its lower end to an outward intermediate point, andis then contracted so that its upper end narrows to a receiving opening2. Within the casing 1 is mounted a plurality of sifting screens 3, 4and 5. The screens 3 are mounted in angular relation in the upperportionof the casing 1, being carried upon the transverse rods 6 and 7.The rod 6 extends through the machine from front to back and supportsthe upper ends of the screens 3. From the rod 6, the screens incline inopposite directions to the rod 7 upon which the lower ends of thescreens are supported. The screens 3 overlie a chute 8, said chuteterminating at its lower end in a conduit 9 which slants toward the rearof the casing l and by means of the bend 10 which passes around the rearend of the screen 5. The screens 4 are secured at their upper ends uponthe rods 11 which are carried in the front and rear walls of the easing1 adjacent the sides 12 at the widest portion of the casing, andconverge 1n a downward direction until their lower ends are carried bythe bars or rods 13. Ad acent the lower ends of the screen 4, andlocated on an incline extending from the rear wall of the casing 1 to alower point through the front wall, is the screen 5, whlchls supportedupon the transverse bars 14 and 15. The screen 5 extends into anextens1on'16 formed on the front part of the casing 1 and forms thebottom of the spout 17, which projects forwardly and downwardly from thefront of the casing 1.

An annulus cover 18 secured tothe bottom of the casing and extension 16provides a means for seating the sifting apparatus upon the top of acan, barrel or other receptacle. At the lower end of the spout 17 isprovided a semi-circular cover and bracket 19, to whose forward straightside is hinged the cover section .20. The cover section 19 1s downwardlyflanged as at 21 and has the free edge of the flange 21 turned inwardlyto provide the channel 22. Into said channel, thereinforced edge 23 ofthe bucket 24 is an, and is therein has by closing the 11d section20over the bucket, said lid section 20 is also flanged as at 25 to inclosethe rim of the bucket. Hinged to the upper end or mouth 2 of the casing1 is the 'device'for attaching the pail containing the ashes to.

the casing 1. Said device consists of a chute portion 26, which ishinged to the rear edge of the opening or mouth 2 upon the hingesannulus 29 provides a flange support for the rim of a pail 30, theannulus 29 standing in a vertical position, and being adapted to swingslightly beyond its vertical position with. the chute 26 so as to emptythe pail of its contents, the cover provided by the annulus having anopening therethrough which corresponds to the section subtended by therear vertical portion of the chute26. Below the annulus 29, the wall 28is provided with a pair of hooks 31 which are, in effect, sheet metalplates provided with flanges for attachment to the wall 28, and havingthe upturned fingers 32 upon which the handle 33 of the pail 30 isadapted to be hooked, in order to lock the pail in position within theannulus 29. tween the cover or annulus 29 and the-chute portion 26, is adoor or plate 34: which is hinged at its upper edge substantially in theapex of the chute portion 26 upon the rod 35, so that it can gravitallyswing upon .a chute with the motion of the chute portion 26 upon thehinges 27. The hinged brace rods 36 and 37 are connected respectively tothe sides of the casing 1, at the upper forward corner, and to the lowerforward corners of the sides ofthe chute 26, said rods 36 and 37 actingas stops to limit the rearward swing of the chute 26. The rod 36 islonger than the rod 37 and has its project ing'end overturned as at 38so that it will "strike against the rod 37 and act as a stop to preventthe rods from having their lon--' gitudinal axes brought into perfectalinement. Surrounding the'mouth 2 and the lower end of the chute 26, isa hood 39, which may be made of foldable metal sections, or may be alsoconstructedof cloth or other suitable flexible material.

the triangularly shaped side pieces 40 and an intermediate section 11,the apexes of the triangular side sections 40 being provided witheyelets 42 which project over the ends of the rod 43' whichformsthepintle of the hinges 27. I

In the operation of my improved appa-v Covering the opening be,

When formed of" flexible material, the hood is constructed of ratus, thepail containing ashes to be sifted is mounted in the chute 26, the rimof the pail being projected into the flange 29, and

the handle or bail 33 being engaged with the hooks 31. This engagementhaving beeneffected, the chute 26 is swung upwardly in a verticalposition so that its mouth extends yondv the verticalposition, the door34: automatically swings open and permits the ashes to drop into thecasing 1. 1 The ashes drop upon the screens 3, upon which they arepartly sifted, the dust dropping into the chute 8. The cinders and theunsifted material drops then by gravity to the screens 4, and from thescreens 4E, the cinders drop tothe screen 5 and pass thence to the spout17, the dust from the siftings of the screens 41 and 5 dropping into thebottom of the casing 1 and thence into thereceptacle upon which theapparatus is mounted.

From the spout 17 the ashes pass into a bucket which has been mountedupon the combination holder and cover 19, the flange of the bucket beingpassed into the slideway 21 and being locked therein by the flange'25.of the cover portion, which is swung downwardly to cover the pail. Thehood 39 covers the joint between-the chute 26 and the mouth 2, so thatall danger of dust escaping from the 1nouth-2 is prevented, so that itis obvious that, bymeans of my improved apparatus one is enabled to siftashes without the usual attendant dust which escapes even from the besttypes of, rotary and other sifters which areat present upon the market.7

What I claim as my invention is 1. An ash sifter-comprising incombination, a casing, a plurality of relatively inelined screensmounted in said casing, said casing having a hopper mouth vand adelivery spout, a chute hinged to said hopper month to drop backwardlytherefrom, and

dropped backwardly therefrom, a flexible coveringfor the joint betweensaid chute and said casing, and means for locking a pail to said chutewhen'thelatter is carried into delivery position.

1. An ash sifter, comprising in combina" tion, a sifter casing, a feedchute hinged to said casing, and means for limiting the relativemovement of said chute, means for covering the mouth of a pail andlocking the latter into dust-proof connection with the chute, and agravity cut-off device for pre- Venting the return of dust out of thechute after the pail has been removed.

In testimony whereof, I affix my signature, in the presence of twowltnesses.
